JULIUS E. HETTINGER, OF CHICAGO, ILLINOIS. I

HEATER FOR AUTOMOBILES.

To all 'whom it mayV concern.'

Be it known that I, J ULiUs E. Herrmann, a citizen of the United States,residing at Chicago, in the county of Cook andState of Illinois, haveinvented certain new and useful Improvements in Heaters for Automobiles,of which the following is a specification.

This invention relates to heaters for heating vehicles or cars such astrucks or automobiles which are driven' by internal combustion engines,and which have water jackets for cooling the en 'nes and radiators for-cooling the water.

ne of the objects of the invention is to-provide means for transferringthe waste heat of the engine, b

liuids, to the body of the machine, so as to warm the persons in themachine, or to protect -any perishable goods which-may be in the trucksfrom injury by becoming too cold. Other objects of the invention are toprovide means for increasing the radiating surface used in coolin thewater, and to provide suitable means Ier using the apparatus either forheating purposes or for additional radiating purposes, as may bedesired. Other objects of the invention will be apparent from a.consideration' ofthe accompanying drawings and the followingdescriptionthereof.

Of the accompanying drawings Figure 1- is an elevation'ofan automobile,with portions broken away, which has mounted there* in certain meansJfor ca ing out my invention; Fig. 2 is a plan view of the engine and`radiator of the machine, together with Athe nclosing casing;

the heater which I use; Fig. Sis an enlar ed plan view of the heater orradiator;

Fig. 5 is an end view' of the heater casing; Fig. 6 is a perspectiveview of one s1de of Fig. 7 is a perspective view of another side of thecasing; and Fig. 8 is a perspective view of a device -As is wellunderstood, it is 4common with automobiles and trucks `tohaveA a' waterjacketed engine and. to have aradiatonin the machine which'is directlyconnectedl with the water jacket, and to which the water -iiows, andAfrom which the heat thereof is A.radiated away, so` that the water inthe jacket may be kept suflicientl cool.- However, inthe apparatus whichuse carryspecineation of Letters Patent.

means of the water, or other suitabletions othe ig. 4 is a section-alongthe line 4-4 of-Fig. 3;

the heater formed by the ipes 12'by meansL of -a pipe 13, to the-top oft e ordinary radiator 14 of the machine, and then by means of `a vpipe15 I connect the bottom of the radiator 14 with the bottom of the'waterj aclretI ofthe engine. v

When the pipes are arranged in the man` i ner specified it will be seenthat there will be a continuous 'flow of water from the water jacketaround through the heater pipes 12, back to the top of the radiator-14`,- and finally vto the bottom ofthe water jacket, due to the coolingof the water in the radiator 14 and in' the pi e 11 and the downwardiiow thereof. At t e same time the water in the heater pipes 12 will be,continually losing heat by radiation from, the pipes,l and this heatwill be used in heating the car.

In orderto prevent dangerof vbreaking the pipes from vibrations andotherwise, and

to provide simple. means for'connecting or disconnecting the ipes, `Iprovide flexible couplin s 16 and 1 to connect various porpipes. In thismanner any strains due to limproper placing of the pipes, or to strainson the automobile itself, will be avoided, and also danger of fractureby Vibrations will be eliminated, and the pipes can be convenientlydetached when desired. For instance if it is desiredto disconnecttheheater itself from the system it is necessary only to disconnect thecouplings 16 and 17 from the ypipes and to connect the two ends of thepipes which are joied to the' front radiator and the engine b means ofthe iiexi'ble tube 18 (Fig. 8) an the circulation of the water willcontinue as before, while the heater itself may be entirely removed.

In order to prevent waste of heat, I inclose a portion of the pipes 11and 13 in a conduit 20 having a` lining 21 of non-conducting substance,and I also inclose the heater itself in a casin 22, the walls of whichhave, in the sides t ereof, non-conducting sheets 23, the bottom 25 ofthe casing being composed iio of a sheet of suitable metal 26 oneachside f of a sheet of non-conducting substance 24.,

such as asbestos. When the heater is to be used for heating purposes theupper surface of the casing 22 is covered by a sheet 27,

through the openings of which the heated air from the pipes is allowedto pass.

However, the sheets 27 and 25 are interchangeable, so that, while incool weather the sheet 27 may be used on the upper surface of the casing22, so as to allow the heated air to pass into the machine, and the.

lsheet may be used for the lower surface so as to prevent heat frompassing downwardly, yet in warm weather the two sheets may be reversed,so that no material amount of heat can pass upwardly into the machine,vbut the'heat may be radiated down freelyl through. the sheet 27 andalso by the sheet sides they are fixed in place in the caslng 22 byymeans of catches 30, so that b simply springing these catches o from te sheets the sheets may be removed and very easily interchanged. Theheater may be composedof an suitable form 'of pipes or chambers. Iy haveshown-in this mstance round pipes for the purpose, but it is to beunderstood that oval or flat pipes may be used if it is desired. Thepipesare supported in the casing by means of cross pieces 31 which' restupon beams 32 extending across the machine from one side of the chassisto the other,- and resting upon the chassis beams 33, the beams 32projecting through the ends of the casing 22, as indicated. Crosspieces'35 hold the provided for running the water out 'ofthe variouspipes firmly in place. By these means the heater pipes may beconveniently removed from the easing or the entire casing may be removedrom the machine, whenever desired. And when the casing is 'removed theopening may be closed by means of the cross bars 32 and the plates 25and 27 resting thereon. Apetcock 34 is piges whenever desired. p

y this means a very effective' and convenient heating apparatus isprovided. The hottest water passes immediately from the water jacket ackinto the machine,'the

hottest' portion of the pipe 11 passing im mediatelyl beneath .the Hoorof the front seat,

through, said pipes, a casing inclosing said pipes, said casing having adetachable heat non-conducting bottom and a detachable metal open worktop, the shape and size of said bottom being substantially the same asthe shape and size of said top, whereby said bottom and top areinterchangeable.-
